WOVEN PIL-E FABRIC.

Our invention relates to improvements in woven pile fabrics, the ob ectofthe invention being to provide a cut pile fabric in which the warppile threads forming the tufts are securely woven into the fabricbacking and project uniformly from the fabric, presenting a smoothunbroken surface.

A further object is to provide a woven pile fabric in which thealternate warp pile threads in any series extend in the same directionfrom one backing fabric to the other, and adjacent pile threads extendin opposite directions from one backing fabric to the other, all pilethreads being uniformly woven into the upper and lower backing fabrics.

WVith these and other objects in View, the invention consists in certainnovel arrangement of threads in the weaving of the fabric as will bemore fully hereinafter described and pointed .out in the claim.

In the accompanying drawings: Figure 1 is an exaggerated view inlongitudinal section illustrating our improved pile fabric.

Figs. 2, 3, and f are views similar to Fig. 1, but each view showing butone pile thread of the series connecting the backing fabrics, and Fig. 5is a diagrammatic plan view of the fabric after the pile is cut.

Our improved pile and bottom backing fabrics X and Y respectively,connected by warp pile threads arranged in series of three threads to aseries, said pile threads given reference numerals 1. 2, and3,'respectively.

The top backing fabric X consists of 6 and 7 and weft.-

binding warp threads threads A, B, C, D, E, and F, woven between 6 and7. The lower backing fabric Y consists of binding warp threads 4 and 5with weft threads A, B. C, D, E, and F woven therein.

The upper and lower picks of the weft threads are simultaneously wovenby the shuttle, and hencefor scription, these pairs of picks of the weftthreads are given corresponding letters, the

reference letters of the picks of the bottom fabric being primed asabove described.

In Fig 1, the series of three pile threads 1, 2, and 3, are illustratedshowing how the several threads are woven into the backing fabrics X andY, and by arrows indicating the direction of the weave of said pilethrea ds.

In Figs. 2, 3, and 4, the backing fabrics are illustrated, and-inconnection therewith one of the threads 1, 2, and 3, respectively isillustrated to show clearly the manner ofweaving the same. Referring tothese Figs. 2, 3, and 4, it will be noted first, that pile thread 1 ispositioned over weft thread A, under weft thread B, thence over weftthread C, thence extends from the top fabric X to the bottom'fabric Y,and passes under weft'thread D, thence over weft thread E, thence underweft thread F, and to the point of starting another series over weftthread A. Pile thread 2 passes over weft thread A in the top fabric X,thence extends to the lottom fabric Y and under weft thread 5 under weftthread D, thence back to the top fabric'X, over weft thread E, andthence under weft thread F to the point of starting another seriesover.weft thread A. Pile thread 3 extends over weft thread A, thenceunder weft thread B, thence to the top fabric X over weft thread C,thence under weft thread D, thence over weft thread E, thence back tothe bottomfabric Y, and

'under weft thread F to the point of starting another series oi. er weftthread A.

By reference particularly to Fig. 1, it will be noted that eachalternate pile thread extends in the same direction from one fabric tothe other, and that each adjacent pile thread extends in opposite onebacking fabric to the other. The pile threads, therefore, maintainthroughout the surface of the fabiic a uniform disposition so that notwo adjacent tufts have a tendency to separate or to cross, allprojecting alike from the backing and insuring a pile fabric ofuniformly smooth and unbroken surface free from ridges, marking todetract from the appearance of the fabric. Furthermore, it will be notedthat each tuft of the pile is tightly woven into the backing fabric andcannot work out of the backing fabric in any ordinary wear.

Various slight changes might be made in thence over weft thread C,thence directions from grooves, or other.

the general form and arrangement of parts described Without departingfrom our invenqtion and hence We do not limit ourselves to the precisedetails set forth, but consider ourselves at liberty to make suchchanges and alterations as fairly fall Within the spirit and scope ofthe appended claim.

Having thus described our invention, avhat We claim as new and deslre tosecure by Letters Patent 1s:

A pile fabric, comprising top and bottom backing fabrics, a series ofthree pile fabric to the other, said backing fabrics consisting of Weftthreads and binding Warp top and bottom fabrics Woven With three of saidshots, and between the binding Warp threads, substantially as described.

In testimony whereof we have signed'our names tothis specification inthe presence of tWo subscribing Witnesses.
